PowerDynamics.jl: An Open-Source Framework Written in Julia for Dynamic Power Grid Modeling and Analysis. The main idea of this package is to turn dynamic power grid models into a right-hand-side function of a DAE system, which can then be solved using OrdinaryDiffEq.jl.

The main features of PowerDynamics are:

• ModelingToolkit.jl based Frontend: Component models such as machines, controllers, power lines, ... are all defined as symbolic, equation-based MTK models.
• NetworkDynamics.jl based Backend: PD.jl generates Julia code for each of the MTK models as NetworkDynamics.jl compatible vertex- and edge models. NetworkDynamics is used to interconnect those bus and edge models.
• Component-Based Initialisation: Annotate your dynamic models with simplified powerflow models. Solve the powerflow and initialize free dynamic states and parameters of the node and edge models to fit the powerflow result.
• Symbolic Indexing and Observables: Use your typical SciML syntax like plot(sol, idxs=VIndex(2,:busbar₊u_mag)) to access arbitrary states, parameters, observables of your MTK models (in this case, the variable named busbar₊u_mag of vertex model 2).

... and there is much more! Please check out the Documentation.
